./'0 altar/ 10m. it may concern Be it known that we, Gnonon THOMSON SANnnnsoN and THoMAs BoLANn, respectively residing at Old Gala House, Galashicls, in the county of Selkirk, Scotland, and 4:5 oodside Place. (ialashiels, atoresaid, have invented certain new and useful Improvements Relating to Driving Apparatus for Spinning, Doubling, and Twisting Machincry of which the following is a specification.

This invention relates to improvements in the method of and means employed tor reversing the direction of rotation of the band cylinders on spinning males and all other spinning and twisting machinery, and also in the ease of mules for controlling the speed of winding. The inule in its present state of construction is titted with two cylinders one at each side of the headstock and reaching to each end of the carriage. These cylinders are driven by a band from the rim pulley to a grooved pulley in the carriage. This grooved pulley is fixed on a shaft on which is also fixed the winding motion, and the backing 0E motion. For reversing the direction of retation of the band cylinders of spinning mules and other spinning and twisting inachinery, it has been proposed to interpose gearing between a driving shaft and the band cylinder or cylinders so that while the driving shatt revolves continually in one direction, the cylinder or cylinders may be revolved in either direction as desired by the manipulation of the intermediate gearing.

According to this invention instead of the drive being transmitted directly to the band cylinder it is transmitted to a countershatt which extends wholly or mainly throughout the length of the machine and drives the cylinder or cylinders at the end or ends that are remote from the headstock or driving end of the machine through the intervention of gearing which is so constructed and arranged that the cylinder or cylinders can be driven in either direction at will and also at a speed which can be regulated to suit any particular class of yarn.

In applying the invention to a spinning mule the hand drive is transmitted from the rim pulley to a counter-shaft which extends wholly or mainly throughout the length of the carriage and drives the cylinder or cyl 192%. Serial No. 720,617.

inders at the end or ends which are remote from the headstock through the intervention of gearing which will enable the cylinder or cylinders to be driven in either direction at will and at any predetermined speed.

The countershajtt is introduced in the mule carriage in the place where the cylinder is ordinarily mounted and the latter is brought forward, or nearer to the centre of the carriage. The hand drive from the rim pulley to the grooved pulley is then transmitted to the counter-shaft instead oi to the cylinder and the drive is transmitted from the countershaft to the cylinder by gearing which is mounted at the end or ends of the carriage as aforesaid and as the countershaft is also driven by the winding motion the winding speed can be controlled by altering the gearing between the cylinder or cylinders and the countershatt.

In applying the invention to a ring spinning, or other like frame the band cylinder or cylinders may be raised and the countersha'tt placed underneath them. In this case the drive would be transmitted to the eoimtershatt at the headstock or driving end ot the machine and from the countershatt to the band cylinder or cylinders through the intervention of gearing as aforesaid at the end of the machine that is remote from the headstock or driving end.

In order that the said invention may be clearly understood and readily carriedinto eil'ect, the same is described more fully with reference to the accompanying drawings which show the invention applied to a spinning mule.

Figure 1 is a plan view ot a mule carriage provided with driving mechanism according to this invention. Figs. 2 and 8 are left and right hand views of the carriage, and are drawn to a larger scale. Fig. 4 is an end view, and Fig. 5 is a plan view. showing the driving mechanism arranged for ordinary direction of driving.

The band cylinders D are placed nearer the center of the carriage B than they are ordinarily placed. and a eountersha'tt E journaled in the carriage parallel to them. A pulley (Z is secured on the countershatt. and is driven by a band 0 from a driving pulley C, and when winding it is driven by the winding motion. Toothed wheels 6 are secured on one or both ends of the shaft E and gear into toothed wheels d on the shaft of the ill) band cylinder as shown in Figs. 2v and 3, when it is required to drive the cylinder in the reverse direction. To drive the cylinder in the ordinary direction the wheels 6 and (Z are replaced by smaller wheels 6 and d, as shown in Figs. 4t and 5, and these small wheels are connected by an idle toothed wheel Gr mounted on a pin g.

Any change can be made in the size of the wheels on the cylinder shaft and countershaft for controlling the speed of winding. If two 4.0 toothed Wheels are necessary for imparting a rninin'nun tension to the yarn when winding, then a to and a 35 toothed wheel or a 43 and 37 toothed wheel or any other change can be made to suit the count or quality of the yarn and any speed at which the cylinder is rotated can be raised or lowered to increase or diminish production.

The details of construction can be variously modified without departing from the nature of the invention, for example any form of change speed gear and reversing gear between the countershatt and the cyl inder can be subst'tuted for the one described.

By the invention described it is possible, in certain classes of yarn, to considerably in crease the speed of the cylinder or cylinders, and in this way there would be an increase in the amount of yarn which could be wound on to each pirn. The spinner can if he so desires use the winding motion without the reverse motion and thus get ordinary twist. For this purpose he could it he so desired, cross his driving bands and drive the band cylinder by two geared. wheels, one on the countershaft and the other on the band cylinder shaft. Uneven yarn produced when the rim pulley is not the exact size required can be eliminated by varying the gearing at the "Hd of the countershaft and cylinder,

and without having to change the rim band pulley. The countershaft acts as a support or stay for the mule carriage and increases its rigidity. The apparatus is extremely simple and it can be applied to any spinning mule, doubling or twisting machinery for spinning, or twisting wool, worsted, linen, jute, silk and other fibres, with very little trouble and at a very small cost.

lVhat we claim as our invention and desire to secure by Letters Patent in the United States is 1. In cylinder drivin apparatus for spinning and twisting mac iinery, the combination of a counte-rsliaft, a band cylinde' arranged parallel with the countershaft, means for transmitting motion to the countershatt. and gearing connecting the eountersha'ft and band cylinder at the end that is remote from the driving end of the machine.

2. In cylinder driving apparatus for spinn'ng mules, the combination with the headstock and carriage, of a countershaft extending along the carriage, a band cylinder arranged parallel with the countershaft, means for transmitting motion to the wuntershatt. and gearing connecting the countershatt and band cylinder at the ends that are remote from the headstock.

3. In cylinder driving apparatus for spinning mules, the combination with the headstock and carriage, of a countershaft extending along the carriage, a band cylinder arranged. parallel witli the countershaft at opposite sides of the headstock. means for transmitting motion to the countershaft. and gearing connecting the counterslrat't and band cylinders at the ends that are remote from the headstock.

In testimony whereof we allix our signa tures.
